I also have found a way to reproduce the crash by calling crashme that
way:

% crashme +2000.0 3306 100 12:00:00 3

I have tried it 3 times now, and the system always hung immediately
after
executing the above command!
It seems to be machine dependent, though. I can only reproduce it with
seed
3306 on system #1 (K6-233, 256MB RAM, Linux-2.0.34pre16, kernel
without
APM configuration!).
I'll check if I can find a similar "100% crash seed" on the other
systems,
too.
